Vickers DG5V Series Valve | DG5V-7-2A | DG5V-8-S-8C | DG5V-7-6C | Pilot Operated Directional Control Valve

DG5V Series Pilot-Operated Directional Valves (NG20 / NG25)

Product Overview: The DG5V Series consists of premium two-stage solenoid-operated directional valves designed for high-flow hydraulic systems. This series combines a solenoid pilot valve (typically DG4V-3) with a large-bore main stage, utilizing pilot pressure to shift the main spool smoothly under high-pressure conditions. Available in Size 7 (NG20) and Size 8 (NG25), these valves are widely used in heavy-duty presses, metallurgical equipment, large injection molding machines, and industrial hydraulic power units. Optional features like VM (Voltage Monitoring) and various pilot/drain configurations ensure maximum system reliability and flexibility.

Featured models: DG5V-7-2A-T-M-U1-H-7-54, DG5V-7-2A-M-U-H7-30, DG5V-8-S-8C-T-S-VM-FTWL-B-10, and DG5V-7-6C-M-U-H5-40.

Key Technical Advantages:

• High-Flow Handling: Engineered for environments exceeding 200 L/min, with peak flow capacities up to 700 L/min, effectively minimizing system pressure drops.

• Pilot Circuit Flexibility: Supports internal/external pilot (X) and internal/external drain (Y) configurations to adapt to diverse manifold logic requirements.

• VM Intelligent Protection: Models such as the DG5V-8-VM integrate voltage monitoring to prevent malfunctions caused by electrical faults.

• Wet-Pin Solenoid Pilot: Equipped with high-performance DC/AC solenoids supporting a 100% Duty Cycle (ED), offering superior longevity and vibration resistance.
